Ants are small and harmless, but they can be so annoying. Just one little crumb can attract a whole bunch and they seem to spread everywhere. To stop them before they even become a problem, combine water, white vinegar, and essential oil in a spray bottle and mist all doors and baseboards in your home.

2. Cockroaches

If cockroaches send shivers up your spine, you need to make this pesticide before they even think about entering your home. Two cups of water mixed with two tablespoons of tea tree oil should do the trick.

3. Spiders

These pesky flies seem to come from nowhere! We don't recommend cutting fruit from your diet so try this fruit fly trap instead. Stir together water and red wine vinegar in a cup. Then create a funnel out of a coffee filter and place it on top. Within a few days, the fruit flies will all be trapped in the cup with no way to escape!

The only place you should be worried about mosquitos is in front of the bonfire. Keep those annoying pests outside this fall by placing lavender, catnip, or basil near any entrances to your home.
